Women are built different, have different bodies, different hormones, and different needs than men do.
If you have ever tried to lose weight at the same time as the man in your life and they instantly drop 15 pounds are you lose 5 pounds doing exactly the same thing as him, then you know what I'm talking about.
Structure and Consistency
Plie squats to work your inner thighs, strapless dress, muffin top, bra fat, thigh dancing, back fat, & saddle bags...need I say more. Exercises that target areas most women want to tone, sculpt, and shed.
Comfortable workout atmosphere when doing killer exercises that are not the most attractive positions.
Women have different needs for their body than men. Men will never fully understand when it is that time of the month, menopause, being a mother, and just being a women.
